Boyfriend in my room

I'm 14 and I've been dating/close with my boyfriend for over a year now. We haven't done anything more than kissing mostly and I'm not even thinking about doing more with him I'm not ready for that. But anyway my house is really boring downstairs and we have nothing to do down there but I have a tv in my room with Netflix and I have a puppy and she sleeps in my room and it's so comfortable in there so how do I convince her to let me hang out with him in there with the door open? 
P.S. Both of my older brother have had girls in their rooms before the set age in our house of 18. So any advice?
